Upper Jurassic-Lower Cretaceous depositional environments and evolution of the Bilecik (Sakarya Zone) and Tauride carbonate platforms, Turkey

Three Late Jurassic-Early Cretaceous carbonate platform stratigraphic sections have been studied in central western Turkey (Bilecik carbonate platform at Bilecik and Saricakaya) and in the Taurides in southern Turkey (Tauride carbonate platform at Beysehir) by using sedimentological and cyclostratigraphical methods. One section was analyzed by detailed magnetic susceptibility measurements. Peritidal carbonates on both platforms display cyclic patterns throughout the sections and do not contain any siliciclastic material. This cyclicity is generally expressed as shallowing upward cycles and interpreted as records of short-term sea-level changes.


Upper Cenomanian-Lower Campanian Derdere and Karababa formations in the Cemberlitas oil field, southeastern Turkey: their microfacies analyses, depositional environments, and sequence stratigraphy
Mülayim, Oğuz; Mancini, Ernest; Çemen, İbrahim; Yılmaz, İsmail Ömer (2016-01-01)
The frontal belt of the southeastern Anatolia fold-thrust belt in Turkey contains several small to mid-size oilfields, producing from carbonate reservoirs of the Cretaceous Mardin group. Many of these fields are found along narrow, asymmetrical anticlinal structures, associated with the formation of the fold-thrust belt. The emberlitas oil field in Adiyaman, southeastern Turkey, is one of the most important oilfields in the region. It produces from the Upper Cretaceous Derdere and Karababa formations of the...
Cenomanian–turonian platform evolution and records of OAE 2 on the drowned northern arabian carbonate platform (se Turkey): Integration of biostratigraphy, sequence stratigraphy, sedimentology, and stable isotopes
Mülayim, Oğuz; Yılmaz, İsmail Ömer; Department of Geological Engineering (2020-10-23)
The evolution of the Cenomanian–Turonian (C–T) carbonate platform (northern Arabian Platform) in southeastern Turkey has been embraced with special emphasis on the sedimentology, biostratigraphy, lithostratigraphy, sequence stratigraphy, and stable–isotope geochemistry. The interplay of different sedimentologic features on the ramp type platform is deciphered on the basis of field and subsurface observations, detailed stratigraphic sections, macrofacies, and microfacies analyses, stable δ 13C and δ ...
Cyclic Carbonate Facies Changes on the Middle to Upper Cenomanian Arabian Carbonate Platform, SE Turkey: An Approach for the Causes of Short- and Long-Term Sea-Level Change
Yılmaz, İsmail Ömer; Mülayim, Oğuz; Sarı, Bilal; Simmons, Mike (2017-08-26)
The studied Cenomanian shallow water platform carbonates of the Derdere Formation lies on the northern Arabian platform in Mardin area, SE Turkey. The sedimentology and cyclic nature of the facies along the studied composite sections have been analysed in terms of cyclostratigraphy. In the lower section, alternations of benthic foraminiferal-algal packstone/wackestone and bioturbated bioclastic wackstone/lime mudstone take place at the base of small scale cycles. Alternations of bivalve/ostracod wackestone/...
Seismic stratigraphy of Late Quaternary deposits on the continental shelf of Antalya Bay, Northeastern Mediterranean
Tezcan, Devrim (2006-09-01)
The Late Quaternary sedimentation and structural features of the continental shelf of Antalya Bay (SW Turkey) have been investigated using a single channel high-resolution shallow profiling system. Two seismic units denoted as unit 1 and unit 2 bounded by two major unconformities (R-1 and R-2) have been identified. R-1 and R-2 are type-1 sequence boundaries that formed under sub-aerial conditions during the Late Quaternary sea level lowstands. An acoustic basement (AB) is recognized in the study region; it ...
Cenomanian-Turonian drowning of the Arabian Carbonate Platform, the Inisdere section, Adiyaman, SE Turkey
Mulayim, O.; Yilmaz, O. I.; Sari, B.; Tasli, K.; Wagreich, M. (Geological Society of London, 2020-01-01)
The Cenomanian-Turonian carbonate ramp in the Adiyaman Region of SE Turkey (Northern Arabian Platform) records an abrupt shift from benthic carbonate deposits to pelagic deposits near the Cenomanian-Turonian boundary event (CTBE) in the Inisdere stratigraphic section and surrounding borehole sections. A positive delta C-13 excursion of up to 2.15% is recorded in carbonate and organic carbon deposited around the CTBE and provides evidence of a direct link between the CTBE and oceanic anoxic events and the de...
